Abstract: 1,174,217. Forging; extruding; drilling. KOBE STEEL Ltd. 30 April, 1968, No. 20527/68. Headings B3C, B3H and B3P. A multi-press comprises a turret 3 supported for rotation about a boss 2 and a series of unit presses 5a, 5b, 5c, 5d arranged to straddle the turret with one pillar 6a of each press extending through the boss and the other pillar 6b outside the periphery of the turret. The presses have a common base 1 and separate upper frames 7.

IPC: G07F11/68
Filed: 1958-06-27
Abstract: 885,733. Coin-freed vending machines. ASSOCIATED AUTOMATION Ltd. June 19, 1959 [June 27, 1958], No. 20643/58. Class 27. A coin-freed machine for issuing stamps, strip tickets or the like comprises a frame 1, a rotatable delivery device for delivering stamps from a storage magazine, a coin-freed means for operating the delivery device, a horizontally-movable member 2 for actuating the coin-freed means, and a resilient connection between the member 2 and coin-freed means of sufficient strength to transmit the required operating force but insufficient strength to transmit a force in excess of such force. As shown in Fig. 5, the member 2 is a push-button having a shank 2B fixed to a tube 2C which has a pin-and-slot connection 2D, 6A with one end of the pivoted operating lever 6 of the coin-freed means, a spring- loaded plunger 2E, 2F provided in the tube being arranged to transmit the operating force to the lever but to absorb such force without effect on the lever should the mechanism be ineffective because, for example, no coin has been inserted, the magazine is empty or the mechanism has developed a fault. The lower end of the lever 6 is formed with a quadrant gear 6C meshing with gears 8A, 9A which mesh with gears 8B, 9B. The gear 8B, which is freely rotatable on a shaft 8 coupled to the stamp magazine, is formed with a cam having detents 8C arranged through a pawl 10A to drive a lever 10 connected to the shaft 8. A coin inserted in a slot 1B passes through a testing device 4 and shoot 4A to a rotary hopper 5 which when rotated by the gear 9B on initial movement of the push-button 2 causes the coin to abut a spring-loaded lever 5B and thereby withdraw an abutment 5D carried by the lever from the path of the coin hopper. Continued movement of the pushbutton causes the shaft 8 to be rotated by the device 10, 10A to deliver a stamp; the lever 10 is prevented from over-travel in one direction by a stop 11 attached to the quadrant gear 6C and' in the other direction by a oneway weight-controlled stop 12. A full-stroke pawl 14 is provided and a spring-loaded blocking pin prevents operation when an empty magazine is being removed. More than one coin may be necessary to operate the machine by providing additional coin slots, shoots and compartments in the coin hopper. Specification 616,524 is referred to.

Title: Spark erosion
IPC: B23H1/02
Filed: 1971-04-19
Abstract: 1342036 Spark-erosion PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [4 Feb 1970] 20748/71 Heading B3V [Also in Division H3] A stabilized voltage source 4 is connected to a spark erosion gap 2 at the beginning of each machining discharge in order to maintain the current density in the gap 2 constant. In one embodiment, Fig. 1, the erosion gap is supplied with pulses from a voltage source or pulse generator 3. At the beginning of each discharge a pulse from a differentiating network C 1 , R 1 , R 2  is applied to the base of a transistor T 3  which switches a monostable multivibrator 5. The latter causes, via transistors T 1 , T 2 , a transistor T to be conductive and a supply source 4 to be connected across the erosion gap 2 until the multivibrator 5 is switched back to its original condition. The transistor switch may be replaced by a thyristor or several transistors connected in parallel. In another embodiment, Fig. 3, the transistor T 3  is replaced by a bistable multivibrator 7. When a pulse appears at the output of monostable multivibrator 5, an amplifier 8 is connected to its supply voltage causing a transistor T to be switched on and a voltage source 4 connected across the spark gap 2. The conductivity of the transistor T is controlled, so as to control the voltage across the gap, by the output voltage of the amplifier 8 which is determined by feeding a signal from a voltage divider R 5 , R 6  connected across the gap, into the amplifier 8 and comparing it with a reference voltage.

Inventor: ROEBUCK DAVID SAM UEL PETRIE
IPC: C07C63/00
Filed: 1948-08-07
Abstract: In the liquid phase oxidation of alkylaromatic hydrocarbons with gaseous oxygen in presence of catalysts, the mixture is contacted after initiation of the reaction with an inorganic adsorbent of the type used in chromatography, when it proceeds to give a better yield of products.  In examples, Brockman's Standardized Alumina is added in stages to assist the oxidation of p-xylene in presence of copper acetyl acetonate, o-xylene with the same catalyst and toluene with cobalt naphthenate, to give among other products tolualdehyde, toluic acid and benzoic acid. Tables show the increased extent of the reaction due to the addition of the adsorbent.  The invention includes the oxidation of methyl benzenes and ethyl benzenes.  Other adsorbents specified include alkaline earth oxides, fuller's earth, and kieselguhr.

The mirrors 4 may be of stainless steel, and may have bevelled edges on the back surface to reduce light obstruction. Constructions are described wherein the obliquity with respect to the projection axis of the stationary virtual image is avoided or reduced by the provision of fixed or moving optical systems to produce an image of the film forming the object used in conjunction with the moving radial mirror system. The obliquity may also be corrected by the insertion of a prism in the light path. Fig. 7 shows apparatus comprising mirrors 4 rotatable within a stationary drum over which the film passes from a spool 15 into the casing 17, the film being driven by a sprocket 14 and guided by rollers 3, 3<a>.
